ECU ready for coding.
Repeat 5 times ignition on/off sequency, after this immo lamp stay lit and the ecu is in programming mode. ECU rewrites Immo eep contents and the key is programmed.

Hi,
No success with another immo box,
immo lamp blinks 3x
Manual says: Fault 3, ID nummber is not input into immo unit after engine cranking

Can not get into programming mode (MIL3 all time).
I got the immo box with one key from same car, trayed with that key, MIL 3.
Trayed to program the 93c56 with dump from mcgywer full with 00.. no success, engine not running with oem dump runs 5sec.

The oem immo box was lucas 28as the box from junkyard lucas 19as, is that the problem?
I searched 28as immo box did not found...
